ROCKSTAR™ Full Width Tow Flap is constructed for outdoor adventures. Our robust black urethane coated aluminum and five-sixteenths inch rubber shield your toys from damaging road debris. These all black mud flaps are concealed under the pickup's body making the hitch optional and easy to change, ideal for pulling fifth-wheel campers. Forget about needing additional hardware or tools and quickly secure your tow flap to the model specific, anti-sailing mounting brackets using yellow zinc linch pins. Prepared for any path, ROCKSTAR™ Full Width Tow Flaps are just what you need.

Recommended mud flap ground clearance is 6 to 8 in. Suggested clearance with a load is 3 in. minimum to prevent mud flaps from dragging. Designed to fit OEM receivers and bumpers, may not fit aftermarket products.

ROCKSTAR™ Full Width Tow Flap Customer Review Man, I sure wish I would have known about this product YEARS AGO! The trailer I purchased had an option to add an air dam/rock guard to it, but that was a $700 plus add on. So I opted not to do it.Additionally, I really disliked the hitch mounted rock guard because most of them required a special trailer tongue. I already have a WeighSafe. For half the cost of an air dam AND I can utilize my existing hitch tongue, ROCKSTAR for the win! It saved the front of my Camaro from everything my truck blasted it's way.

ROCKSTAR™ Full Width Tow Flap Customer Review Absolutely love this product. Its on all the time. Because it's underneath the bumper, I can run it through a car wash VS the hitch mount style. I can change out my receiver hitches as needed for the boat or camper also because it's mounted underneath the bumper. If on the rare occasion I have to take it off it's super simple just pull 2 pins.

ROCKSTAR™ Full Width Tow Flap Customer Review Love these things. I pull my boat back and forth from Texas to Louisiana and after one trip without mud flaps I had tons of rock chips. I ordered these and they worked amazing. Definitely worth the investment and I love how you can remove it easily with 2 pins. Such an easy and well built system!

Very nice fairly easy to install, only issue where exhaust comes out does not line properly. Cut out needs to go a little further to the right

This mudflap is a great product. Assembly is easy and only takes about 30 minutes. Attaching and removing the mudflap is very easy and can be done in less than 60 seconds. I highly recommend this product.

ROCKSTAR™ Full Width Tow Flap Customer Review I purchased this product, after looking at other brands, mainly for the design and craftmanship. I have to say I could not be happier. I use it to protect my camper while towing and it has performed flawlessly. I like it so much I'm buying another one for my new truck. Stop thinking about it, just buy one! you will not regret it.

ROCKSTAR™ Full Width Tow Flap Customer Review It's really nice having a flap that will provide protection to the front of my Enclosed NEO Trailer and will work with any Hitch on the Market. Plus it can't rock up and down on the end like Hitch mounted ones do.

ROCKSTAR™ Full Width Tow Flap Customer Review Great product! From form to fit and function everything is great and works as advertised. The product looks factory correct on my all black Denali. The full width tow flap is perfect at keeping my boat, car hauler, and blacked out enclosed trailers looking amazing. Thanks!

ROCKSTAR™ Full Width Tow Flap Customer Review After trying several different hitch mounted mud flaps, I found these online. All I can say is WOW. Easy installation and they do a great job protecting my boat. Even if I'm not towing, I like to keep them on since they look so good on the truck!

ROCKSTAR™ Full Width Tow Flap Customer Review The Rockstar tow flap is a fiberglass saver! We throw the tow flap on every time we are moving our boats so the tires don't kick any rocks up at the bow of the bow. Install was super easy. I love that we can remove the flap when we don't need it but quickly (within seconds) reinstall the flap with the spring clips. The flap offers tons of protection and it looks great!

Review by: Gerry M. - ME   star star star star star

shipping was fast. install was simple, but, instructs were a little odd. Photos always look at photos never read instructions. Over all really happy with this. Cuts the splash up onto trailer by 75% will never stop all but helps alot.

Review by: Lynn H. - SD   star star star star star

This is the third Item I have ordered from you and I am very happy with all three. Two before rear bumper and one hitch mounted full length mud flaps. one for each of my trucks. I like the before bumper more, but the hitch mount allows for other trucks to use while using my trailers.

ROCKSTAR™ Full Width Tow Flap Customer Review Spectacular product!!! Very easy to assemble and install, no more that 40mins and it's ready to go! After the trailer was attached to my F-150, the tow flap was about 3-4 inches off the pavement, perfect! Drove about 200miles, no issues. Love the protection that it provide against small rocks, gravel, and such for the trailer.

I like the full med flap. I had a question and called the company, they were very helpful. I would definitely buy this product again.

Review by: Andy B. - OH   star star star star star

These under bumper mount tow flaps are great. They are much easier to put on/off than hitch mounted tow flaps. They are well constructed and appear that they will have a long service life.

Review by: Kent R. - TX   star star star star star

I am very happy with these tow flaps. I had an issue with them and it was resolved immediately. This company stands behind its products. I would not hesitate to recommend ACI for any of their products and will absolutely be using them again in the future.

Review by: Mike M. - PA   star star star star

The full tow flap seems to work well for keeping stones from chipping my boat. It's well made but didn't quite fit the brackets after mounting them on the truck. I had to bend the aluminum plates a little bit to fit over the brackets. But overall I recommend it.
